Cyclone V LVDS differential termination

In the pin planner I specified input termination as differential for LVDS inputs. Do I need to specify for both positive and negative signals or just one? It seems to work both ways which bother...

you may check the fit report for those two ways

Looks like that helped.

If I only assign termination to the positive then both positive and negative termination are off in the fitter report.

So it appears you have to assign termination to both positive and negative in the pin planner.

Thanks
